β¦ Synopsis
Abstract
Immunostimulants from various microorganisms were tested on a myeloid leukemia cell line (Ml) for the ability to induce production of CSF and to cause differentiation of these cells. Based on their activities, the compounds were divided into two general classes: those inducing extensive cellular differentiation and those devoid of this effect. The stimulants which were active in this regard always produced large quantities of CSF, whereas those devoid of a differentiating effect did not cause CSF production. Even the potent stimulants had no effect on the D^β^ subline, in which the differentiation was not inducible.

The growth of the human leukemia cell line AML-193 in a serum-free medium is strictly dependent o n the presence of the cytokine granulocyte-macrophage COIL ony-stimulating factor (GM-CSF), which is one of the major regulators of the myelomonocytic lineage. At present, little is known about the mech
